Authorization Authentication Method And Apparatus

ABSTRACT

A third-party application client performs authorization authentication with a user client and a platform server. The third party application obtains an access token and an open ID. The third-party application client interacts with the platform server for information related to the user ID by using the token, calls the user client or is called by the user client according to the open ID. The third-party application client may interact with the platform server for the information related to the user ID by using the token, so that other resources or information of the user accumulated for the platform server can be used by the third-party application client continuously.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/CN2013/076566 filed on May 31, 2013. This application claims the benefit and priority of Chinese Application No. 201310156187.X filed Apr. 28, 2013. The entire disclosures of each of the above applications are incorporated herein by reference.

FIELD

The present disclosure relates to an authorization authentication method and apparatus.

BACKGROUND

This section provides background information related to the present disclosure which is not necessarily prior art.

Along with the developments of Internet technologies, different service providers have made various services available, such as e-mail, Instant Messaging (IM) services, social networking and, resource downloads, etc.

When using Internet services, the user usually needs to log on to a server of the service provider by using a registered user name and password. When there are multiple service providers, the user has to perform multiple registering procedures. Hence, service provider A may authorize service provider B to use the registered user name and password of the user via an open platform mode, so that the user may use the same registered user name and password when logging on to different service providers. For example, service provider A that provides “XX MicroBlog” services may authorize service provider B that providers “XX forum” to use a MicroBlog account and password of the user if service provider A is permitted by the user, so that the user does not need to register for the “XX forum”, and may log on the “XX forum” by using the MicroBlog account and password which are registered for “XX MicroBlog”, and use the services provided by the “XX forum”.

The above-described systems have the following limits. After service provider A authorizes service provider B to use the registered user name and password, the user may directly log on to the service provider B, and only the registering operations are omitted. The whole authorization authentication procedure is terminated and other accumulated resources or information of the user for service provider A cannot be used by service provider B continuously.

DETAILED DESCRIPTION

Various embodiments will now be described more fully with reference to the accompanying drawings.

Specific examples of the present disclosure will be illustrated in detail hereinafter with reference to the accompanying drawings, so that the above and other characteristics and merits of the present disclosure are clear.

FIG. 1 is a diagram illustrating a structure of an implementation according to various embodiments of the present disclosure. The implementation circumstance includes a third-party application client 120, a user client 140, and a platform server 160.

The third-party application client 120 is a first type of client running on a terminal. The first type of client may be a client provided by service provider B, e.g. a forum client, a mail client, a MicroBlog client, an entertainment client, etc.

The user client 140 is a second type of client running on the terminal. The second type of client may be a client provided by service provider A. Usually, service provider B has numbers of users and a buddy relationship chain between the users. The third-party application client 120 and the user client 140 may be running on the same terminal, and the third-party application client 120 may communicate with the user client 140 via a Software Development Kit (SDK) provided by the user client 140.

The platform server 160 is a background server provided by the service provider A, and is to provide services provided by the service provider A for users when combining with the user client 140. The platform server 160 may communicate with the user client 140 and/or the third-party application client 120 via a wired network or wireless network.

The above-mentioned terminal may be a smart phone, a tablet PC, an e-book reader, a Moving Picture Experts Group Audio Layer III (MP3), Moving Picture Experts Group Audio Layer IV (MP4), laptop and desktop computers, etc.

Several terms in the various embodiments are described, by way of non-limiting example, as follows.

An application identifier (ID), called application ID for short, is to identify an identity of the third-party application client 120 on the platform server 160, and may be obtained by the third-party application client 120 via registering procedure on the platform server 160.

A user identifier (user ID) is to identify an identity of the user on the platform server 160, and may be obtained after the user performs a registering procedure via the user client 140 on the platform server 160.

An authorization instruction is an instruction sent to the user client after the user authorizes the third-party application client 120.

An author code is a code sent to the third-party application client 120 for obtaining a token after the platform server 160 determines that the third-party application client 120 has authorized by the user.

An access token, also referred to as a token, is a token sent to the third-party application client 120 for interacting information related to the user ID with the platform server 160, after the platform server 160 determines that the third-party application client 120 has authorized by the user; the token has several interface calling permissions of the platform server 160.

An open identifier, also referred to as an open ID, is an identifier generated according to the application ID and the user ID and is used to replace the user ID in the third-party application client, so as to avoid directly sending the user ID to the third-party application client by the platform server 160. In other words, the identity of the user is identified by the open ID in the third-party application client.

FIG. 2 is a flowchart illustrating an authorization authentication method according various embodiments. In the various embodiments, the authorization authentication method is applied in the implementation circumstance shown in FIG. 1, and includes the following processing.

Block 201: the third-party application client sends an authorization request to the user client. The authorization request carries an application ID of the third-party application client. Correspondingly, the user client receives the authorization request from the third-party application client.

Block 202: the user client sends the application ID and a user ID to the platform server, after obtaining an authorization instruction. Correspondingly, the platform server receives the application ID and the user ID from the user client after the user client obtains the authorization instruction.

Block 203: the platform server sends an authorization code to the user client according to the application ID and the user ID.

Block 204: the user client receives the authorization code from the platform server and transmits the authorization code to the third-party application client. Correspondingly, the third-party application client receives the authorization code sent by the platform server.

Block 205: the third-party application client sends the application ID and the authorization code to the platform server. Correspondingly, the platform server receives the application ID and the authorization code from the third-party application client.

Block 206: the platform server obtains a token for the third-party application client according to the application ID and the authorization code.

Block 207: the platform server sends the token to the third-party application client. Correspondingly, the third-party application client receives the token from the platform server.

Block 208: the third-party application client interacts with the platform server for information related to the user ID via the token. The information related to the user ID includes user information, a buddy relationship chain, and information related to the third-party application client. The user information includes at least one of a nickname, an avatar, and a signature.

According to the authorization authentication method provided by the various embodiments, the third-party application client interacts with the platform server for the information related to the user ID by using the token, thereby solving the problem in the prior art that only the registering operations are omitted and other accumulated resources or information of the user for service provider A cannot be used continuously. The third-party application client may interact with the platform server for the information related to the user ID by using the token, so that other resources or information of the user accumulated for the platform server can be used by the third-party application client continuously.

FIG. 3A is a flowchart illustrating an authorization authentication method according to various embodiments. In the various embodiments, the authorization authentication method is also applied in the implementation circumstance shown in FIG. 1. In this example which is a preferable example based on the various embodiments, the user client is a “Xchat” client provided by the service provider A providing IM services, the third-party application client is a “recite words” client provided by the service provider B providing words reciting services, the “Xchat” client and “recite words” client are running at the same terminal, and the service provider A has numbers of user and a buddy relationship chain corresponding to each user. The authorization authentication method includes the following processes.

Block 301: the third-party application client sends an authorization request to the user client. The authorization request carries an application ID of the third-party application client. The third-party application client sends the authorization request to the user client via a SDK provided by the user client in advance, when the third-party application client needs to obtain the authorization. The authorization request carries the application ID of the third-party application client.

For example, in reference to FIG. 3B, when the third-party application client “recite words” is running on the terminal of the user, if the user does not want to register for the third-party application client “recite words” but wants to directly logs on and use the third-party application client “recite words” by using the user ID registered for the user client “Xchat”, the user clicks a button 311 of “directly log on via a Xchat account” on an interface 31 of the third-party application client “recite words” to trigger the third-party application client “recite words” to send the authorization request to the user client “Xchat”. The authorization request carries the application ID of the third-party application client “recite words”.

Correspondingly, the user client receives the authorization request from the third-party application client. That is, the user client receives the authorization request from the third-party application client via the SDK provided for the third-party application client in advance.

Block 302: the user client sends the application ID and the user ID to the platform server, after obtaining an authorization instruction. The user client sends the application ID and the user ID to the platform server, after obtaining the authorization instruction. For example, in reference to FIG. 3C, after the user clicks the button 311, the interface 31 of the terminal switches to an interface 32 of the user client “Xchat”. The interface 32 shows contents of the authorization 321 requested by the third-party application client “recite words”. If the user agrees with the authorization, the user clicks a button 322 of “agree” to send the authorization instruction to the user client “Xchat”. The user client “Xchat” sends the application ID and the user ID to the platform server after obtaining the authorization instruction. Correspondingly, the platform server receives the application ID and the user ID from the user client after the user client obtains the authorization instruction.

Block 303: the platform server sends an authorization code to the user client according to the application ID and the user ID. After receiving the application ID and the user ID sent by the user client, the platform server determines that the user has authorized the third-party application client, and sends the authorization code to the user client according to the application ID and the user ID.

Block 304: the user client receives the authorization code from the platform server and transmits the authorization code to the third-party application client. The user client receives the authorization code from the platform server and transmits the authorization code to the third-party application client via the SDK provided in advance. The procedure is imperceptible of the user. Correspondingly, the third-party application client receives the authorization code sent by the platform server.

Block 305: the third-party application client sends the application ID and the authorization code to the platform server. After obtaining the authorization code, the third-party application client needs to obtain the corresponding token by using the authorization code. The third-party application client sends the application ID and the authorization code to the platform server. Correspondingly, the platform server receives the application ID and the authorization code from the third-party application client. The platform server does not directly send the token to the third-party application client in block 303, but sends the authorization code first, so as to ensure the security. The token is sent to the third-party application client when the platform server directly communicates with the third-party application.

Block 306: the platform server obtains the token for the third-party application client according to the application ID and the authorization code. The platform server obtains the token for the third-party application client according to the application ID and the authorization code. The token has a permission to call at least one interface of the platform server. The interface includes at least one of a user information interface, a buddy relationship chain interface, and an information sending interface.

Block 307: the platform server sends the token to the third-party application client. Correspondingly, the third-party application client receives the token from the platform server.

Block 308: the platform server generates an open ID according to the application ID and the user ID. The platform server generates an open ID according to the application ID and the user ID. The open ID replaces the user ID in the third-party application client. Specifically, the platform server may combine the application ID and the user ID and encrypts the combination to generate the open ID. The platform server may store a relationship of the application IDs, user IDs, open IDs, tokens, and interface call permission corresponding to the tokens, as shown in FIG. 3D.

Block 309: the platform server sends the open ID to the third-party application client. The platform server sends the open ID to the third-party application client. Correspondingly, the third-party application client receives the open ID from the platform server. The open ID is generated by the platform server according to the application ID and the user ID, and is to replace the user ID in the third-party application client. The platform server will not reveal the user ID to the third-party application client, and the third-party application client only can obtain the open ID and identify the identity of the user by using the open ID.

Blocks 309 and 307 may be performed at the same time, that is, the platform server sends both the token and the open ID to the third-party application client. In the various embodiments, the blocks 309 and 307 are described separately, which is not limited in the present disclosure.

Block 310: the third-party application client stores the open ID, and associates the open ID with the token. The third-party application client interacts with the platform server for information related to the user ID via the token. That is, the platform server interacts with the third-party application client for information related to the user ID via the token. The information related to the user ID includes user information, a buddy relationship chain, and information related to the third-party application client. The user information includes at least one of a nickname, an avatar, and a signature.

Bock 311: the third-party application client obtains the user information related to the user ID from the platform server via the token. The user information includes at least one of a nickname, an avatar, and a signature.

The third-party application client obtains the user information related to the user ID from the platform server via the token. The user information includes at least one of a nickname, an avatar, and a signature. In other words, the platform server provides the user information related to the user ID for the third-party application client via the token.

In reference to FIG. 3E, block 311 may include the following sub-blocks. 311 a: the third-party application client calls the user information interface from the platform server according to the open ID and the token. For example, the third-party application client sends a first request to the user information interface, and the first request is to obtain the user information corresponding to the user ID. Because the open ID replaces the user ID in the third-party application client, the first request includes the token and the open ID. Correspondingly, the platform server receives the request for calling the user information interface from the third-party application client according to the open ID and the token. For example, the platform server receives the first request sent by the third-party application client to the user information interface, and the first request includes the token and the open ID.

311 b: the platform server checks whether the token has the permission to call the user information interface.

311 c: when determining that the token has the permission to call the user information interface, the platform server returns user information corresponding to the open ID, and the user information includes at least one of a nickname, an avatar, and a signature.

311 d: the third-party application client receives and stores the user information corresponding to the open ID.

Afterwards, the third-party application client may use the user information accumulated by the user on the platform server. For example, the third-party application client “recite words” may directly use the nickname, avatar, and signature accumulated by the user on the platform server, so that the nickname, avatar, and signature of the user on the third-party application client “recite words” and the user client “Xchat” are the same.

Block 312: the third-party application client obtains the buddy relationship chain related to the user ID from the platform server via the token. In other words, the platform server provides the buddy relationship chain related to the user ID for the third-party application client via the token.

In reference to FIG. 3F, block 312 may include the following sub-blocks.

312 a: the third-party application client calls the buddy relationship chain interface from the platform server according to the open ID and the token. For example, the third-party application client sends a second request to the buddy relationship chain interface and the second request is to obtain the buddy relationship chain corresponding to the user ID. Because the open ID replaces the user ID in the third-party application client, the second request includes the token and the open ID. Correspondingly, the platform server receives the request for calling the buddy relationship chain interface from the third-party application client according to the open ID and the token. For example, the platform server receives the second request sent by the third-party application client to the buddy relationship chain interface, and the second request includes the token and the open ID.

312 b: the platform server checks whether the token has the permission to call the buddy relationship chain interface.

312 c: when determining that the token has the permission to call the buddy relationship chain interface, the platform server returns an open ID of at least one buddy which is in an original buddy relationship chain corresponding to the open ID and also authorizes the third-party application. For example, user A has 10 buddies in the original buddy relationship chain on the platform server, i.e. buddies A1 to A10. Buddies A1, A3, and A7 also authorize the third-party application while other buddies do not authorize the third-party application. In the example, the platform server does not directly send the original buddy relationship chain including the 10 buddies to the third-party application client, but sends a buddy relationship chain including the buddies A1, A3, and A7 to the third-party application client. In the buddy relationship chain, buddies A1, A3, and A7 are identified by using the open IDs corresponding to buddies A1, A3, and A7.

312 d: the third-party application client stores the open ID of the at least one buddy as a buddy relationship chain of the open ID in the third-party application client. Afterwards, the third-party application client may use the buddy relationship chain accumulated by the user on the platform server, which includes the following processes.

312 e: the third-party application client obtains attribution values respectively corresponding to the open ID and open IDs of the at least one buddy on the third-party application client. The attribution value may be a level, scores or contribution values accumulated by the user on the third-party application client. For example, the attribution value of the user on the third-party application client “recite words” may be the number of words recited by the user. For the user A, the third-party application client may obtain the number of words recited by user A, buddy A1, buddy A3, and buddy A7 at the same time.

312 f: the third-party application client creates an attribute ranking according to the attribute values. For example, the third-party application client “recite words” obtains the number of words recited by user A, buddy A1, buddy A3, and buddy A7 on the third-party application client, and creates an attribute ranking for the four users, as shown in FIG. 3G.

Block 313: the third-party application client sends the third-party information related to the user ID to the platform server via the token. The third-party information includes information related to the third party application client. The third-party application client sends the third-party information related to the user ID to the platform server via the token. The third-party information includes information related to the third party application client. Correspondingly, the platform server receives and processes the third-party information related to the user ID from the third-party application client via the token.

In reference to FIG. 3H, block 313 may include the following sub-blocks.

313 a: when the third-party information needs to be sent, the third-party application client calls an information sending interface from the platform server according to the open ID and the token. When the third-party information needs to be sent, the third-party application client sends a third request to the buddy relationship chain interface, and the third request is to send the third-party information to at least one buddy corresponding to the user ID. Because the open ID replaces the user ID in the third-party application client, the third request includes the token and the open ID and an open ID of a target buddy. The at least one buddy is included in the original buddy relationship chain corresponding to the open ID and authorizes the third-party application. Correspondingly, the platform server receives the request for calling the buddy relationship chain interface from the third-party application client according to the open ID and the token. For example, the platform server receives the third request sent by the third-party application client to the information sending interface, and the third request includes the token, the open ID, and the open ID of a target buddy.

For example, when the number of words recited by the user A reaches 10000, the third-party application client generates third-party information “the number of words recited by the user A reaches 10000”, and sends the third request to the platform server. The third request includes the token, the open ID of the user A, the open IDs of target buddies A1, A3, and A7, and the third-party information “the number of words recited by the user A reaches 10000”.

311 b: the platform server checks whether the token has the permission to call the information sending interface.

311 c: when determining that the token has the permission to call the information sending interface, the platform server sends the third-party information to some or all of the buddies. For example, when determining that the token has the permission to call the information sending interface, the platform server sends the third-party information “the number of words recited by the user A reaches 10000” which is sent by the user via the third-party application client “recite words” to the buddies A1, A3, and A7.

According to the authorization authentication method provided by the various embodiments, the third-party application client interacts with the platform server for the information related to the user ID by using the token, thereby addressing that only the registering operation is omitted and other accumulated resources or information of the user for service provider A cannot be used continuously. The third-party application client may interact with the platform server for the information related to the user ID by using the token, so that other resources or information of the user accumulated for the platform server can be used by the third-party application client continuously.

In addition, the third-party application client obtains the user information and/or the buddy relationship chain from the platform server via the token and sends the third-party information to the platform server via the token so that the resources and information accumulated by the user for the third-party application client and the platform server, respectively, are shared in the authorization scope.

FIG. 4A is a flowchart illustrating an authorization authentication method according to various embodiments. In the various embodiments, the authorization authentication method is also applied in the implementation circumstance shown in FIG. 1. In this example, the third-party application client and the user client call each other. The authorization authentication method includes the following processes. Blocks 401 to 410 are the same or similar, and are not described herein.

Block 411: the platform server sends the open ID to the user client. The platform server sends open ID to the user client. Correspondingly, the user client receives the open ID from the platform server. The open ID is generated by the platform server according to the application ID and the user ID, and is used to replace the user ID on the third-party application client.

Block 412: the user client stores the open ID and associates the open ID with the user ID. The user client stores the open ID and associates the open ID with the user ID. Afterwards, the user client and the third-party application client call each other according to the open ID. The third-party application client and the user client call each other according to the open ID. The calling procedure may be implemented based on the SDK provided in advance, and includes the following processes.

Block 413: the user client sends a request for calling the third-party application to the third-party application client. The request for calling the third-party application may be used to start the third-party application client. For example, in reference to an interface 41 shown in FIG. 4B, the user is using the user client “Xchat” on the terminal and wants to start the third-party application client “recite words”, the user clicks a button 411 of “recite words” on the interface 41 to trigger the user client “Xchat” to send the request for calling the third-party application to the third-party application client. The request for calling the third-party application carries the open ID associated with a current user ID. The current user ID is an identifier of a user currently logging on as the user client. Usually, the current user ID of the terminal is unchanged. If another user logs on to the user terminal, the current user ID may be changed. Correspondingly, the third-party application client receives the request for calling the third-party application from the user client.

Block 414: the third-party application client checks whether the open ID associated with the current user ID is identical with the open ID associated with the token. For the purpose of checking whether the current user has changed, the third-party application client checks whether the received open ID associated with the current user ID is identical with the locally stored open ID associated with the token. If yes, the current user is not changed, otherwise, the current user has changed.

Block 415: if it is determined that the open ID associated with the current user ID is identical with the open ID associated with the token, the third-party application client responds the request for calling the third-party application. If it is determined that the open ID associated with the current user ID is identical with the open ID associated with the token, the third-party application client starts and runs by using the open ID to identify the user logging on currently.

Block 416: the third-party application client sends a request for calling the user client to the user client.
